The discovery of Mirror Neurons in Macaque monkeys has lead to theories of the neurophysiological substrate of speech perception being grounded in mirror neurons. This is also relevant to the evolution of speech as if ability to perceive a rapid stream of phonemes is present in species such as macaques then this provides a foundation on which . . . → Read More: Are mirror neurons the basis of speech perception?...

By: Dr. Ken Broda-Bahm - Watching the Wizard of Oz recently with my three (and a half!)-year-old daughter, we came to the familiar scene of the fearless Toto interrupting the Wizard’s speech by pulling back the curtain on a man furiously working levers and wheels. When Dorothy and company ignore the instruction to “pay no attention to the man behind the curtain,” it becomes clear that what we see of the ‘wizard’ is an elaborate façade. There is a similar façade at work during jury se........ Read more »

New research touts findings that conservatives have bigger amygdalas while liberals have bigger cingulate cortices. The bigger amygdala means conservatives could be driven by fear while the bigger cingulated cortex means liberals have more decision-making power. Hmmm. Is it possible that our politics are fixed at birth? Probably not. Neuroskeptic takes a look at the [...]

Image source: FlickrMany ecological systems have tipping points - thresholds where small changes in impacts can have very large effects on on ecosystem functioning, often in a bad way. Lakes, for example, might show little impact from nutrient pollution until a threshold level is reached, and then massive algal blooms form that choke off many other species growth.
In the absence of knowledge of exactly how far one can push a system before reaching a tipping point, many invoke the precautio........ Read more »

In the year AD 1098 a spruce tree was chopped down in the Chuska Mountains, which run roughly along what is now the border between Arizona and New Mexico. We don’t know who cut it down, exactly, since the people living in the area at the time had no system of writing and have therefore [...]... Read more »
Since Thorstein Veblen’s 1899 book Theory of the Leisure Class, the economics profession has taken a somewhat mixed approach to consumption.

Conspicuous consumption has a purpose as a signal. However, [...]... Read more »

So, on to the paper by Robert Rowthorn, which I see now has even been picked up by the Denver Post!
Just to explain a bit of the background. Rowthorn is an economist, and his paper is basically a model of what would would happen if you have a gene (strictly speaking [and for Bjørn's benefit], an allele) that predisposes for membership of a group, and if that group has high reproduction.
What he shows is that the gene spreads incredibly quickly - just 10 generations after it appears, 80% of t........ Read more »

If you have ever had the pleasure of being in a boisterous Tokyo bar at night, eating and drinking amongst a din that would sear the armour off a tank,you get the feeling that this is what pure, hedonistic joy must be like. And, according to this article by Ikeda et al. (2011), Japanese men love it as well.
